We found detections of water vapour and winds in the atmospheres of hot Jupiters HD 189733 b and HD 209458 b

The JEM-EUSO (Joint Experiment Missions for the Extreme Universe Space Observatory) program aims at developing Ultra-Violet (UV) fluorescence telescopes for efficient detections of Extensive Air Showers (EASs) induced by Ultra-High Energy Cosmic Rays (UHECRs) from satellite orbit. In order to demonstrate key technologies for JEM-EUSO, we

162173 Ryugu, the target of Hayabusa2, is a spinning top-shaped asteroid. Observations by Optical Navigation Camera onboard Hayabusa2 have shown that the western side of this asteroid possesses a smooth surface and a sharp equatorial ridge, compared to the other side. Here, we propose that a rotationally-driven deformation process generated the

We present an analysis of the spectroscopic properties of the Lixiaohua asteroid family, which hosts two main-belt comets. This study will enhance our knowledge of how primitive asteroids were formed and the abundance of their water reservoir. Mapping the water abundance among the Solar System small body populations is a key constrain to understand

We describe the Sloan Digital Sky Survey (SDSS) as an archetypal mid-scale program, including the technical, scientific, and organizational aspects underpinning its success over the last twenty years. Based on the SDSS experience, we present six recommendations that the funding mechanisms for mid-scale programs should be designed to ensure.

We study the behaviour of the dynamical and stellar mass inside the effective radius of early-type galaxies (ETGs) as a function of environment considering Newtonian dynamics, different surface-brightness profiles, different initial mass functions (IMF), and different redshift ranges. We use several samples of ETGs - ranging from 19 000 to 98 000
